Hello!!!,
I’m starting to use vtkCameraPass/SequencePass/RenderPassCollection primarily for the purpose of display outline highlights and using environmental lighting. I’m not saying I fully understand how it works, but I am able to get the effects I need 
In the very near future I’ll need to start using different sequences of passes in different render windows - for example to use a Skybox in one window but a plain/gradient background in another.
My problem is that I cannot see how the Camera passes can be asociated to any specific renderer/renderwindow? It seems that these are somehow defined and applied globally?
Or am I missing something?
Thanks in advance - Doug
